Ibikoresho bya OLED byisi yose Ababikora batwara udushya muri Next-Gen Yerekana Ikoranabuhanga

Ibikoresho bya OLED byisi yose Abakora ibinyabiziga bitwara udushya mu kwerekana

Ikoranabuhanga rya Organic Light-Emitting Diode (OLED), ryamenyekanye nkibisekuru bizakurikiraho byerekana ibisubizo bikurikira CRT, PDP, na LCD, bikomeje guhindura inganda za elegitoronike nibikorwa byayo byiza kandi bihindagurika. Gukoresha ibikoresho bya semiconductor organic bitanga urumuri munsi yumuriro wamashanyarazi, OLED itanga igishushanyo mbonera cya leta guhuza ibyiza bya CRT's itandukaniro ryinshi na LCD'umwirondoro, mugihe cyo gukuraho inzitizi z'umurage.

Imiterere ya OLED n'imikorere

Igikoresho gisanzwe cya OLED kigizwe nuburyo bwinshi bukora, harimo anode, urwego rwo guteramo umwobo (HIL), urwego rwo gutwara umwobo (HTL), urwego rwohereza ibintu (EL), urwego rwo gutwara ibintu bya elegitoronike (ETL), urwego rwa elegitoronike (EIL), na cathode. Izi nzego zakozwe kugirango zikore a“ingazi”urwego rwingufu (Igishusho 1), byoroshya guhuza neza imyobo na electron murwego rwoherejwe kugirango bitange urumuri. Ubuhanga bugezweho bwa doping burusheho kunoza urwego rwingufu (Imbonerahamwe 1-2), kuzamura ibikoresho neza nigihe cyo kubaho.

Ibikoresho by'ingenzi byo gukora

Umusaruro wa OLED ushingiye ku bikoresho kabuhariwe bigenewe matrike ya pasiporo (PM-OLED) na tekinoroji ikora (AM-OLED). Sisitemu zingenzi zirimo:

PM-OLED: Ibikoresho byo guhumeka hamwe nibikoresho bya ensapsulation.

AM-OLED:  Sisitemu yo kubitsa: Ibibanza bisohora, plasma-yongerewe imbaraga ziva mumashanyarazi (PECVD), hamwe na vacuum yumuriro (VTE) kubice bya tristoriste yoroheje (TFT).

Ibikoresho byo gushushanya: Coater, imashini zerekana, hamwe na ethers yumye / itose yo guhimba imirongo ya TFT.

Sisitemu ya Annealing: Amatanura, imiyoboro ya gaze, nibikoresho bya laser.

Kugerageza & gusana: TFT yipimisha amashanyarazi, OLED isesengura optique, hamwe nimashini zo gusana laser.

Urwego mpuzamahanga rutanga ibikoresho bya OLED rwiganjemo inganda zihariye muri Koreya yepfo n’Ubuyapani, aho usanga abapayiniya binganda batwara udushya mu kubika neza, gushushanya, no gukoresha ikoranabuhanga. Ibigo bikomeye byashimangiye imyanya yabyo binyuze mu iterambere mu bicuruzwa biva mu mahanga kandi bitanga umusaruro ushimishije. Niingirakamaro kubikorwa byinshi bya OLED ikoreshwa muri terefone zigendanwa, TV, nibikoresho byambara.
